For the existing HSDPA network already has an extension. HSPA evolution, HSPA + or evolved HSPA called in the English-speaking world, promises faster network access for traveling. HSPA evolution is an extension of the already known process of HSPA (high-speed packet access). Introduction, speeds are expected in the downstream 28 MB / second and 11 MBit / s in the uplink. HSPA evolution achieves these speeds through a better use of the available frequency space of the UMTS network.

HSPA is established in Austria evolution with these values based on Ericsson technology. Already 42 MBit per second were shown in a demonstration network in the vicinity of Stockholm. Supposedly an existing HSPA can be infrastructure via software update on this speed evolution. The increased speed is achieved by MIMO (multiple input, multiple output). It heitsst, it works only if the mobile device in range of at least two fixed points and antenna systems.

In this case, that joins Mobile device with two fixed points and transmits the data divided parallel to both. Doubling the transmission speed is accesible theoretically by the doubling of the connection. However, it remains to be seen how the system works in practice. Especially in areas of high network load – so there, where many users at the same time online – going evolution with HSPA could it be that this multiplication is achieved not up because simply not enough free benchmarks available. How can such a power load without construction of additional benchmarks balance only practice can show. Conclusion: With HSPA evolution is a similar to VDSL mobile solution based on the exist UMTS infrastructure conquer the market. Torsten Heinsius

More and more users choose mobile Internet prepaid. A fixed Internet connection, until recently, for many, was the best way to take advantage of the World Wide Web. But mobile to use the Internet to check his emails at any time, on the way to download the latest music download or watch videos on platforms like YouTube, is growing in popularity. This is always cheaper mobile Internet prepaid. This is ensured via the mobile phone or an Internet surf stick.

The wide range of offers in the Prepaidbereich is increasing. Now the advantage that no long term must be used, makes prepaid so interesting. This allows a high degree of flexibility in the comparison. Only the power claim is paid. There are different Prepaidvarianten. A daily flat rate is ideal for people who don’t take the Internet claim. For frequent surfers a month flat rate is interesting. A daily flat rate is available from 2 euro.

Monthly flat rates there are from 20 euros. So everyone must Users know which is the better Prepaidvariante for him. The purchase prices for the surf sticks and their SIM cards can be very different. Here it starts at prices from 30 euros. However, care should be given. Roughly, it can be said that low tariffs go hand in hand with expensive sticks and vice versa. The access to the World Wide Web via the already described surf sticks. This is quickly connected to a USB port thanks to plug -and-play. Usually the software is already installed on the Internet sticks. With a few clicks, it is then ready to surf. Christopher Heinsius
